With Office 2007 & 2010 coming up with a Ribbon, Struggling to find where the command / feature you used in Office 2003 was, might not be uncommon. Having spend time 'searching' for the commands myself I understand the pain.
A nice tool from Microsoft Research came to the rescue. The Final version known as the "Office 2007 Search Commands Tool" , it was a neat plugin. ( read = needs to be installed + overhead of a Plugin ).
You can download it from here. http://www.officelabs.com/projects/searchcommands/Pages/default.aspx
Unfortunately it was not updated for Office 2010 but then something better came up; An interactive guide. This Application will display an image of Office 2003 / 2007 from where you can select the option you want, the Equivalent in Office 2010 is immediately displayed.
Here is where you can access the interactive guide.
